This is an interesting paper. The figure 8 schematic
was of particular interest. It looks like the top half
is just a state-variable filter. I wonder if my module
would work? Also the differential hysterical portion
looks like it might need a change. Putting clamp
diodes on the output of an LM324 doesn't seem like a
good idea. I think I would either put a 1k resistor on
the outputs of the 324 where it goes into the diodes,
or else switch to a TL084 which has internal
resistors.

I may just have to build one of these.
